There are 2 squat racks at my gym. One guy loads up 6-45 lb plates and waits for his buddy to spot, waiting for 10 plus minutes until buddy shows up. Guy sits downs on a nearby bench texting and playing with music.

In the meantime the other squat rack is tied up. I could have been done with my 100 squats by the time his buddy shows. He does 10 reps.
